A wavelet transform boundary coefficient is one subject to circular filter
operations (or other boundary treatments). Conversely, the interior transform
coefficients are those that are not affected by the imposed boundary treatment.
The `wavBoundary`

function separates the boundary coefficients from the interior
wavelet transform coefficients.
